Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cableway baskets, in particular to an adjustable cableway basket for inclined curtain walls. BACKGROUND

[0002] A cableway basket is a high-altitude working device suspended on the outer side of a building and pulled by a steel cable or a track system, mainly composed of a metal basket body carrying working personnel and tools, a suspension support structure, a driving and braking device, and widely used in the construction, decoration, cleaning and maintenance, and curtain wall installation of high-rise buildings. It can be flexibly lifted and moved along the facade of the building, allowing construction personnel to reach the high-altitude working surface without the need to set up scaffolding, thus saving material and time costs and adapting to the working needs of different building forms. Its design emphasizes structural stability and safety protection, and is equipped with anti-falling and overload protection devices, which is a key equipment for improving construction efficiency and ensuring safety in modern high-rise building facade engineering. The first paragraph searches for the historical background and development process of this product on the Internet.

[0003] However, the running track and working range of the traditional basket system are strictly limited, and it can only adapt to vertical curtain walls and facade curtain walls without modeling changes, realizing simple vertical up and down running construction, and being difficult to meet the personalized needs in modern building curtain wall design. When facing inclined or complex shaped curtain walls with internal retreat and collection, the traditional basket usually needs to be displaced multiple times to cover all working surfaces, and even needs to be repeatedly set up support structures. This series of complicated processes not only greatly increases labor input, leading to an increase in labor costs, but also consumes more materials such as scaffolding and connecting pieces, causing an increase in material costs. At the same time, the frequent adjustment and construction process will seriously affect the construction efficiency. In addition, when adjusting to these special structures, the traditional basket also needs additional installation and debugging work. During the debugging process, the suspension system, braking device, running track and other components need to be finely calibrated to ensure their safety and stability under special working conditions. After debugging, according to industry standards and safety requirements, joint detection and acceptance by the construction party, supervision party, third-party detection institutions and other parties are required. Only after confirming that it is completely qualified can it be put into use again. This series of links not only further occupies the construction time, but also may need to be rectified again due to problems found during the detection process, or the delay of the acceptance process, bringing great uncertainty to the construction period control of the entire project, and in severe cases, it may even cause the project progress to lag behind the plan.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0036] Embodiment one: please refer to Figures 1-5The application discloses a kind of adjustable cableway hanging basket for inclined curtain wall, including cableway system 3 installed on building 1 and the suspension platform 5 of sliding installation on cableway system 3, wherein, building 1 is traditional modern building 1 or some personalized buildings 1 with inclined curtain wall, and the current conventional inclination angle range of modern inclined curtain wall personalized building 1 is: 5°-30°.In traditional modern building 1, the facade of such building 1 is mostly vertical structure, and the cableway system 3 (including upper support point 31, lower support point 32 and steel wire rope 33) of the application can be arranged in vertical trajectory by fixing upper support point 31 on the top of building 1 and fixing lower support point 32 on ground platform 2, so as to replace traditional vertical hanging basket to complete construction and meet the basic operation requirements of traditional modern building 1; and for personalized building 1 with inclined curtain wall, the installation position of upper support point 31 on the top of building 1 and the installation position of lower support point 32 on ground platform 2 can be adjusted, so that the extension trajectory of steel wire rope 33 is parallel to the inclined surface of building 1, thereby solving the technical pain point that traditional hanging basket cannot adapt to inclined curtain wall.

[0037] Please refer to Figures 1-5 Cableway system 3 includes upper support point 31 and lower support point 32, upper support point 31 is fixedly arranged on the top of building 1, lower support point 32 is fixedly arranged on ground platform 2, steel wire rope 33 is fixedly arranged between upper support point 31 and lower support point 32, both ends of steel wire rope 33 are fixed to upper support point 31 and lower support point 32, and the extension trajectory of steel wire rope 33 is completely coincident with the connecting line between upper support point 31 and lower support point 32.When building 1 is inclined curtain wall, steel wire rope 33 is in inclined trajectory, so that the running direction of suspension platform 5 is parallel to the working surface. In order to meet the inclination angle of inclined curtain wall, the installation angle between upper support point 31 and lower support point 32 needs to be controlled in the range of 0°-30°.

[0038] Please refer to Figures 1-5, two groups of rotating pulleys 51 and fixed pulleys 52 are arranged on the upper and lower ends of the suspension platform 5 and are slidably installed on the steel wire rope 33, the fixed pulleys 52 are fixedly installed on the suspension platform 5, the design provides a stable support reference point through the fixed pulleys 52, and the rotating pulleys 51 realize dynamic angle adjustment. Among them, the fixed pulleys 52 are provided with a rope groove matched with the steel wire rope 33, the rope groove can constrain the steel wire rope 33 to always be in the rim working area of the fixed pulley 52, avoid the steel wire rope 33 from being laterally deviated in the sliding process, and ensure that the suspension platform 5 stably runs along the track of the steel wire rope 33. The rotating pulleys 51 are also provided with a rope groove and a anti-disengagement rod 53, the rope groove ensures that the rotating pulley 51 and the steel wire rope 33 always maintain reliable contact, and avoids that the two contact parts are disengaged due to angle adjustment. When the curtain wall is inclined to cause the angle deviation of the suspension platform 5, the steel wire rope 33 generates a lateral pressure on the rotating pulley 51, drives the rotating rod 511 to rotate, and makes the rotating pulley 51 adjust the position in real time, so that the pulley axis line always keeps parallel with the steel wire rope 33. The double-pulley cooperative mechanism ensures that the platform can be parallel to the working surface in any inclined working condition, and can eliminate the defects that the traditional hanging basket needs to be repeatedly adjusted manually.

[0039] Please refer to Figures 1-5 The rotating pulley 51 is fixedly connected with a rotating rod 511, the rotating rod 511 is rotationally connected to the suspension platform 5 through a torsional spring mechanism, the rotating rod 511 and the torsional spring mechanism constitute a core adjustment system, and the radial pressure of the steel wire rope 33 is converted into a rotating action. When the platform is inclined, the pressure of the steel wire rope 33 drives the rotating rod 511 to rotate against the pre-tightening force of the torsional spring, and drives the rotating pulley 51 to deflect and correct the position. The torsional spring mechanism provides a controllable elastic restoring force, which allows necessary angle adjustment and inhibits excessive shaking. Moreover, the hinging point of the rotating rod 511 is lower than the pulley axis, forming a pressure amplification lever. The torsional spring is a close-coil helical spring, and the pre-tightening force is set according to the weight of the platform. When the relative angle between the steel wire rope 33 and the suspension platform 5 changes, the rotating pulley 51 drives the rotating rod 511 to rotate under the pressure of the steel wire rope 33, so that the axis line of the rotating pulley 51 and the fixed pulley 52 always keeps parallel with the steel wire rope 33.

[0040] Please refer to Figures 1-5, installation, first of all, the basket system 4 is installed on the roof of the building 1, the steel wire rope 33 cableway is arranged at the position from the ground platform 2 to the top of the building 1, the steel wire rope 33 cableway adopts the steel wire rope 33 with a diameter of 8.3mm, and the upper supporting point 31 is fixed on the 12 channel steel cantilever beam arranged at the roof layer of the building 1. The lower end supporting point is fixed by using the pin shaft 341 with a diameter of 25mm in the tied way and the 12 channel steel support on the galvanized embedded plate, the 12 channel steel support is welded with the 200*300*10mm galvanized steel plate, and the galvanized steel plate is fixed by using four M16 chemical anchors. The fixed pulley 52 and the rotating pulley 51 are hung on the suspension platform 5, the suspension platform 5 is lifted along the steel wire rope 33 along the slope by the elevator 42, and the normal construction of the inclined facade is carried out. Among them, the steel wire rope 33 has a transverse component force when the present application is inclined to run, the elevator 42 needs to additionally bear the load increment caused by the component force, and the load limit of the upper supporting point 31 and the lower supporting point 32 needs to be matched, so the rated lifting load needs to be 1.5-2 times of the total load.

[0041] Please refer to Figures 1-5 In the installation process, the basket system 4 is installed on the inclined building 1 structure roof. The upper supporting point 31 is connected with the building 1 by M16 chemical anchor bolt through 200*300*10 galvanized steel plate. The 12 channel steel support is firmly welded with the 200*300*10 galvanized steel plate, and the 60*60*5 galvanized steel square tube is welded with the 12 channel steel. Then the pin shaft 341 is installed on the 12 channel steel. The lower supporting point 32 is connected with the ground platform 2 by M16 chemical anchor bolt through 200*300*10 galvanized steel plate. The 12 channel steel support is firmly welded with the 200*300*10 galvanized steel plate, and then the pin shaft 341 is installed on the 12 channel steel. Then the basket bolt 34 is installed on the upper end of the steel wire rope 33, and the steel wire rope 33 is connected with the pin shaft 341 of the upper supporting point 31, and the basket bolt 34 is installed on the lower end of the steel wire rope 33, and the basket bolt 34 is connected with the pin shaft 341 on the lower supporting point 32. Among them, the elevator 42 drives the suspension platform 5 to be lifted from the ground platform 2 and runs up and down along the cableway steel wire rope 33.

[0042] Please refer to Figures 1-5, the working surface of the building 1 is an inclined surface, and the extension trajectory of the steel wire rope 33 is kept parallel to the inclined surface of the building 1 by adjusting the installation positions of the upper support point 31 on the top of the building 1 and the lower support point 32 on the ground platform 2. The extension direction of the steel wire rope 33 is completely matched with the inclined surface of the curtain wall by adjusting the positions of the upper support point 31 and the lower support point 32. The design of the cableway ensures that the suspension platform 5 moves along the normal direction of the curtain wall. The top layer of the building 1 is fixedly installed with a gondola system 4 for driving the suspension platform 5 to move along the steel wire rope 33, and the gondola system 4 includes a suspension device 41 fixedly arranged on the top layer of the building 1 and a hoist 42 with a driving end connected to the suspension device 41 and fixedly installed on the suspension platform 5 and driving the suspension platform 5 to slide along the steel wire rope 33.

[0043] Please refer to Figures 1-5 The upper support point 31 is fixed on the top of the building 1 by means of a channel steel cantilever beam, and the lower support point 32 is fixedly installed on the ground platform 2 by means of a channel steel support. The channel steel can provide the best bending and torsional resistance, and the flange structure facilitates reliable connection with the building 1. The upper channel steel cantilever beam disperses the load to the load-bearing structure of the building 1, and the lower channel steel support resists uneven ground settlement through a large-area bottom plate. The two ends of the steel wire rope 33 are connected with flower basket bolts 34, and the upper support point 31 and the lower support point 32 are fixedly installed with pin shafts 341 connected with the flower basket bolts 34. The flower basket bolts 34 realize infinite precise adjustment of the tension of the steel wire rope 33, and the pin shafts 341 provide the freedom of universal rotation. Thus, the problem of cableway relaxation caused by temperature deformation is solved, and additional stress caused by wind load is released. Rotating the flower basket bolt 34 can adjust the sag of the cableway, so as to ensure the best tensioning state under different working conditions. The fixed pulley 52 and the rotating pulley 51 are further provided with anti-slip rods 53 for preventing the steel wire rope 33 from slipping, and the fixed pulley 52 and the rotating pulley 51 are further provided with rope grooves. The rope grooves constrain the steel wire rope 33 to run in the middle, and the anti-slip rods 53 form a physical barrier to prevent the steel wire rope 33 from jumping out of the groove. In the inclined working condition, the double measures completely eliminate the risk of the steel wire rope 33 slipping out. The deep groove design increases the contact wrap angle of the steel wire rope 33, and the gap of the anti-slip rod 53 is smaller than the rope diameter, so that even sudden shaking can ensure absolute constraint.

[0044] Please refer to Figures 1-5, the load bearing of the suspension platform 5 shall be set as 500-800kg, during the operation, the weight of the workers (75kg per capita) plus the construction tools and the suspension platform 5 itself, the suspension platform 5 can bear about 2-3 workers. Since the suspension platform 5 includes components such as rotating pulley 51 and fixed pulley 52, the total weight is applied vertically downward by gravity, and the contact points of the rotating pulley 51 and the fixed pulley 52 with the steel wire rope 33 form pressure, therefore, during the operation of the suspension platform 5 along the steel wire rope 33, if the suspension platform 5 has a relative angular deviation with the inclined curtain wall, the center of gravity of the suspension platform 5 will change, causing the force direction of the suspension platform 5 to the steel wire rope 33 to deviate; this deviation causes the steel wire rope 33 to generate a radial pressure perpendicular to the axis of the rotating pulley 51 at the contact point of the rotating pulley 51, this pressure acts on the rim of the rotating pulley 51, and is converted into a torque that drives the rotating lever 511 to rotate; the rotating lever 511 rotates around its hinge axis under the action of the torque, overcoming the elastic restoring force provided by the torsional spring mechanism and the linear resistance applied by the telescopic rod 61; the rotating pulley 51 deflects synchronously with the rotating lever 511, thereby dynamically adjusting the position of the rotating pulley 51, and making the line connecting the axis of the rotating pulley 51 and the axis of the fixed pulley 52 always parallel to the extension direction of the steel wire rope 33, thereby ensuring that the suspension platform 5 can run parallel to the curtain wall operation surface under any angle of inclination, and at the same time, if the suspension platform 5 tilts or shakes during operation, the elastic force of the torsional spring mechanism can be used to realize reciprocating damping, and the telescopic rod 61 provides additional cushioning effect, the two work together to absorb vibration energy, reduce the shaking amplitude, shorten the shaking period, and through position correction, the suspension platform 5 quickly recovers to the parallel state with the steel wire rope 33, forming a self-stabilizing mechanism, thereby effectively suppressing the frequency and weakening the strength of the shaking, ensuring the suspension platform 5 to run stably under complex conditions.

[0045] Embodiment two: please refer to Figures 6-11 To solve the problem of lack of emergency braking mechanism and no effective restriction on the rotation range of the rotating lever 511 in embodiment one, which may cause safety hazards and insufficient angle adjustment stability. In the specific embodiment two, a plurality of brake structures 54 are arranged equidistantly on the suspension platform 5 in the direction from the rotating pulley 51 to the fixed pulley 52, and the equidistant arrangement of the brake structures 54 matches the moment of inertia difference at different positions of the platform, so that the braking force is evenly distributed; the brake structure 54 is provided with a wedge-shaped brake groove 541 which is coplanar with the steel wire rope 33.

[0046] Please refer to Figures 6-11, the wedge structure generates exponential growth of frictional resistance by using the principle of geometric self-locking. When the steel wire rope 33 is embedded into the brake groove 541 due to the inclination of the suspension platform 5, the steel wire rope 33 will form a surface contact with the brake pad 542 on the inner wall of the brake groove 541. At this time, the radial pressure of the steel wire rope 33 on the brake pad 542 will be decomposed into two components along the wedge-shaped groove wall: one is the normal pressure perpendicular to the surface of the brake pad 542, and the other is the tangential component parallel to the wedge contraction direction. Among them, the tangential component will drive the brake pad 542 to slide along the wedge contraction direction (i.e. towards the narrow end of the brake groove 541), wherein the smaller the wedge angle, the greater the proportion of the tangential component, and the stronger the sliding trend of the brake pad 542. The coplanar characteristic of the brake groove 541 ensures that there is no eccentric load impact when braking is triggered, eliminating the stress concentration problem caused by traditional point contact.

[0047] Please refer to Figures 6-11 When the work personnel on the suspension platform 5 moves, the construction tool stack position changes, or the load distribution is uneven, causing the center of gravity of the suspension platform 5 to deviate from the initial equilibrium position, or when the work personnel needs to stop the suspension platform 5 urgently, by actively adjusting the center of gravity, the suspension platform 5 is inclined to the steel wire rope 33. When the suspension platform 5 is inclined to one side of the steel wire rope 33, the pressure of the steel wire rope 33 acting on the rotating pulley 51 is greater than the preset rotation resistance of the rotating rod 511. The pressure of the steel wire rope 33 drives the rotating rod 511 to rotate, reducing the angle between the suspension platform 5 and the steel wire rope 33, so that the brake structure 54 approaches the steel wire rope 33 and the steel wire rope 33 is embedded into the brake groove 541, and the brake groove 541 holds the steel wire rope 33 to stop the suspension platform 5.

[0048] Please refer to Figures 6-11, the suspension platform 5 is also fixedly installed with a cross plate 6, the cross plate 6 is rotatably installed with an extension rod 61 providing a pushing force for the rotating rod 511, and the cross plate 6 is also provided with a sliding groove 62 limiting the rotating range of the rotating rod 511, the rotating rod 511 is rotatably connected with a connecting swing rod 63 connected with the extension rod 61, and the connecting swing rod 63 is slidably connected with the sliding groove 62. The cross plate 6 is made of high-strength, corrosion-resistant and wear-resistant carbon structural steel or low-alloy structural steel, such as Q235B carbon structural steel or Q345B low-alloy high-strength steel, and the surface is treated by hot galvanizing or anti-corrosion spraying. The cross plate 6 is a control base of the rotating rod 511, and the extension rod 61 and the sliding groove 62 constitute an angle limiting system. The extension rod 61 provides a controllable pushing force to maintain the initial position of the rotating rod 511, and the sliding groove 62 converts the rotating angle into linear displacement through the connecting swing rod 63. The extension rod 61 is an elastic extension rod 61, and a nitrogen spring is built in to provide a constant pushing force. When the rotating rod 511 is rotated under the pressure of the steel wire rope 33, the connecting swing rod 63 moves along the trajectory of the sliding groove 62, which not only provides rotating damping but also limits the maximum deflection angle to prevent the mechanism from overloading and failing.

[0049] Please refer to Figures 6-11 The brake structure 54 is fixedly connected between the suspension platform 5, and the brake groove 541 is slidably connected with a brake pad 542 made of flexible material, wherein the brake pad 542 is made of polyurethane elastomer, aramid fiber reinforced rubber and other high molecular composite materials, and the brake pad 542 adopts a detachable structure, which is convenient for subsequent wear replacement. The sliding direction of the brake pad 542 is along the wedge-shaped contraction direction of the brake pad 542, and the brake pad 542 and the brake structure 54 are provided with a sliding rod 543, and the brake pad 542 and the sliding rod 543 are vertically slidably connected. The sliding rod 543 is provided with two groups or more than two groups of sliding rods 543 equidistantly along the vertical direction of the brake pad 542, and the two groups of sliding rods 543 and the brake structure 54 are provided with a pressure spring 544.

[0050] Please refer to Figure 11, in the process of the suspension platform 5 tilting towards the steel wire rope 33, because the line between the rotating pulley 51 and the fixed pulley 52 is always parallel to the steel wire rope 33, and the fixed pulley 52 remains stationary, while the rotating pulley 51 changes its rotation angle as the center of gravity of the suspension platform 5 changes, so when the suspension platform 5 tilts towards the steel wire rope 33, it will gradually move the side of the suspension platform 5 closer to the steel wire rope 33, until the side of the suspension platform 5 is parallel to the steel wire rope 33, and in this process, the brake structure 54 on one side of the suspension platform 5 will come into contact with the steel wire rope 33; when the steel wire rope 33 comes into contact with the brake structure 54, the steel wire rope 33 first embeds into the opening area of the wedge-shaped brake groove 541; at this time, the contact point of the steel wire rope 33 on the brake pad 542 generates a radial pressure, which is decomposed into a normal pressure perpendicular to the surface of the brake pad 542 and a tangential force parallel to the wedge-shaped groove wall. The tangential force drives the flexible brake pad 542 to slide and displace in the wedge-shaped contraction direction, while the normal pressure causes the brake pad 542 to elastically deform, forcing the brake pad 542 to form full contact with the steel wire rope 33, and in this process, the compression spring 544 below the brake pad 542 is preferentially compressed due to the change in angle and position of the brake pad 542, increasing the initial wrap angle pressure of the brake pad 542 on the steel wire rope 33. As the brake pad 542 continues to slide along the wedge-shaped groove, the geometric constraints of the wedge-shaped structure of the brake groove 541 cause the opening distance of the brake pad 542 to decrease nonlinearly, greatly increasing the contact area between the brake pad 542 and the steel wire rope 33, and the compression amount of the compression spring 544 increases with the displacement gradient, and at the same time, the self-locking effect is generated by the wedge angle of the brake groove 541, so that the frictional resistance between the brake pad 542 and the steel wire rope 33 increases exponentially. At this time, the elastic potential energy of the compression spring 544 is converted into braking work, and the kinetic energy is absorbed through the cohesive deformation of the flexible brake pad 542, ultimately achieving gradual and non-impact braking of the suspension platform 5. And as the inclination angle of the suspension platform 5 increases, the symmetry axis of the wedge-shaped brake groove 541 gradually coincides with the direction of the steel wire rope 33; in this process, the embedding depth of the steel wire rope 33 in the brake groove 541 increases exponentially with the decreasing angle, forcing the flexible brake pad 542 to continuously slide along the wedge-shaped groove wall to the narrow end. Thus, the gradient of the frictional resistance between the brake pad 542 and the steel wire rope 33 increases, and finally a rigid self-locking is formed under the cooperative deformation of the compression spring 544 and the brake pad 542, achieving non-impact stopping.

[0051] Example Three: Please refer to Figure 12 To solve the problem of uneven braking response of the brake structure 54 at different heights of the suspension platform 5 in Example Two, and the difficulty of the upper brake structure 54 to quickly contact the steel wire rope 33 at a small inclination angle, which may lead to uneven distribution of braking force. In a specific embodiment, the size of several groups of brake structures 54 is designed to increase in the vertical upward direction of the suspension platform 5, and the brake groove 541 is enlarged in proportion to the brake structure 54.

[0052] Please refer to Figure 12 When the suspension platform 5 is slightly inclined, the distance between the upper position and the steel wire rope 33 is usually farther due to the difference in the spacing between the different height positions and the steel wire rope 33. By increasing the size of the upper brake structure 54, these brake structures 54 can be close to the steel wire rope 33 when the suspension platform 5 is slightly inclined, avoiding the situation that they cannot participate in braking due to being too far away. Thus, when the suspension platform 5 is slightly inclined, not only the lower brake structure 54 can contact the steel wire rope 33, but also the upper larger brake structure 54 can synchronously contact the steel wire rope 33, so that multiple brake structures 54 can generate frictional resistance to the steel wire rope 33 when the suspension platform 5 starts to incline, thereby enhancing the sensitivity of braking, avoiding the failure of a single brake structure 54 due to excessive force, dispersing the braking force, reducing the load of a single structure, and further prolonging the average service life of the overall brake structure 54. When the inclination angle gradually increases, each group of brake structures 54 can be deeper in cooperation with the steel wire rope 33 for braking, and the braking effect is gradually enhanced through the synergistic effect of multiple brake structures 54.
